6dffef6308 spirv: Refactor a couple of pointer query helpers
This commit moves them both into vtn_variables.c towards the top, makes
them take a vtn_builder, and replaces a hand-rolled instance of
is_external_block with a function call.

93646fb503 spirv: Refactor the base case of offset_pointer_dereference
This makes us key off of !offset instead of !block_index.  It also puts
the guts inside a switch statement so that we can handle more than just
UBOs and SSBOs.

94ca8e04ad spirv: Add vtn_fail and vtn_assert helpers
These helpers are much nicer than just using assert because they don't
kill your process.  Instead, it longjmps back to spirv_to_nir(), cleans
up all the temporary memory, and nicely returns NULL.  While crashing is
completely OK in the Vulkan world, it's not considered to be quite so
nice in GL.  This should help us to make SPIR-V parsing much more
robust.  The one downside here is that vtn_assert is not compiled out in
release builds like assert() is so it isn't free.

16dfdeefc8 spirv: Rework logging
This commit reworks the way that logging works in SPIR-V to provide
richer and more detailed logging infrastructure.  This commit contains
several improvements over the old mechanism:

 1) Log messages are now more detailed.  They contain the SPIR-V byte
    offset as well as source language information from OpSource and
    OpLine.

 2) There is now a logging callback mechanism so that errors can get
    propagated to the client through debug callbak extensions.

fa8c1b92b7 glsl: don't run intrastage array validation when the interface type is not an array
We validate that the interface block array type's definition matches.
However, previously, the function could be called if an non-array
interface block has different type definitions -for example, when the
precision qualifier differs in a GLSL ES shader, we would create two
different types-, and it would return invalid as both definitions are
non-arrays.

We fix this by specifying that at least one definition should be an
array to call the validation.

e9eb3c4753 spirv: Use correct type for sampled images
We should use the result type of the OpSampledImage opcode, rather than
the type of the underlying image/samplers.

This resolves an issue when using separate images and shadow samplers
with glslang. Example:

    layout (...) uniform samplerShadow s0;
    layout (...) uniform texture2D res0;
    ...
    float result = textureLod(sampler2DShadow(res0, s0), uv, 0);

For this, for the combined OpSampledImage, the type of the base image
was being used (which does not have the Depth flag set, whereas the
result type does), therefore it was not being recognised as a shadow
sampler. This led to the wrong LLVM intrinsics being emitted by RADV.

688d695868 glsl: Make #pragma STDGL invariant(all) only modify outputs.
According to the GLSL ES 3.20, GLSL 4.50, and GLSL 1.20 specs:

   "To force all output variables to be invariant, use the pragma

       #pragma STDGL invariant(all)

    before all declarations in a shader."

Notably, this is only supposed to affect output variables.  Furthermore,

   "Only variables output from a shader can be candidates for invariance."

It looks like this has been wrong since we first supported the pragma in
2011 (commit 86b4398cd1).

Fixes dEQP-GLES2.functional.shaders.preprocessor.pragmas.pragma_fragment.

v2: Now that all cases are identical (other than compute shaders, which
    have no output variables anyway), we can drop the switch statement
    entirely.  We also don't need the current_function == NULL check;
    this was a hold over from when we had a single var_mode_out for both
    function parameters and shader varyings, in the bad old days.
